Notes:

1. Channel latency is a function of cable length L [m]. The typical value is given by the formula L/(0.7*c),

where c = 3*10E+8 [m/s].2. The shown maximum skew value corresponds to a cable length of 100 meters. The typical skew in a 5-

meter cable is 100 ps and in a 100-meter cable is 200 ps.

VII. Environmental Specifications

Finisar C.wire active optical cables have an operating temperature range from 0C to

+70C case temperature.

Case Operating Temperature Top 0 70 C

Storage Temperature Tsto -40 85 C

VIII. Regulatory Compliance

Finisar C.wire active optical cables are RoHS-6 Compliant. Copies of certificates areavailable at Finisar Corporation upon request.

C.wire active optical cables are laser eye safe so long as the fiber cable is intact. In case ofa broken cable, the C.wire active optical cable should be treated as Class 1M per EN60825-2. If the cable is broken, laser radiation may be hazardous if the cable end is

viewed with magnifying optics.

Standard fiber cable type is s LSZH/riser-rated, flat ribbon construction. Other cable types

are available upon request.

IX. Mechanical Specifications

The C.wire active optical cable mechanical specifications are based on the CXPSpecification, substituting the MPO connectors with a cable connecting both ends.
